Product Introduction
Y-CTK/series zero-sequence transformers are designed for collecting zero-sequence current signals. Zero-sequence current is mA level and must be used in the core-through method, which has high requirements for balance characteristics and linearity.
This series of products has a wide measurement range, rated primary current range: 100mA~5A rated secondary current range: 0~0.25mA, and excellent and advanced manufacturing process. Its accuracy level, reliability and other technical requirements are guaranteed. This series of products meets the requirements of GB-14287.2-2005 and GB14287.2-2014.
Product Features
1. Core-through structure, flame-retardant epoxy resin casting, good stability.
2. High magnetic permeability nickel steel or nanocrystals are used, with good linearity and high sensitivity
3. Excellent balance characteristics and strong anti-electromagnetic field interference ability
Application
Electrical fire monitoring, fire leakage system, small current grounding system, electromagnetic relay protection, microcomputer protection, etc.
